Jason Finger is the co-founder and former CEO of Seamless who now invests at Upper90, focusing on either niche markets with little competition or very large markets where his experience building one of the first successful online food-ordering platforms helps him spot patterns in marketplaces and logistics-heavy businesses. He specializes in financing new-economy asset classes where technology and data can predict cash flows, using creative combinations of credit and equity to help founders keep more ownership while staying deeply involved with a small number of companies rather than spreading investments thin.
